To a]! w]; om it may concern:

I lie it known that l (lixioxron W. Common, oi the city of Toronto, in the Province cl? Untorio, Canada, have made certain new i in llircular Metal Roots, of which the follmving n spccllicalion.

This invention relates particularly to roots for granaries, silos or other circular stru lztures and my object to devise a roof which while still", strong andv weatherproof may be put together with a minimum of labor and that without requiring any special skill on the part of the builder. 1 attain iny object by means of the special arrangement 01" the apex. ousting, redial angle hers, roof sections, cap strips and connections hereinafter described. and illustrated in the acconipanying drawings in which* Figure 'l is a view in elevation of a metal granary constructed in accordance with my invention; Fig. 2 is a plan view of the some; Fig. 3 ie a plan view partly broken away on an enlarged scale of part of the roof; Fig. +l is a crossesection of part of the roo'f partly broken away; Fig. 5 is a plan View partly broken away of the central casting; Fig. 6 is a vertical cross section of the same; Fig. 7' is a cross-section on an enlarged scaleo'l one of the joints of, the root.

In the drawings like numerals ol reference indicate corresponding parts in the different figures.

1 is the wall of the granary, which as usual is formed of corrugated sheet metal. The granary is provided with the usual door 2 and. a discharge spout 3.

The present invention relates particularly to the roof and it must he understood that the construction I shall describe well adapted For all forms ol' circular root or sky-lights as well. as for granary rool's.

The roof supportsromprise a series ol radial bars ii. To give strength and stillness these are preferably formed as cross-shaped angle bars preferably formed by bending up sheet metal as shown particularly in Fig. 7. finch angle bar at its outer end has a cast "all bracket 5 riveted thereto. The lower rib of each angle bar, it will be noted on reference to Fig. i, is cut away to enable the wall bracket to be secured in place.

The upper surface (it the wall bracket is rabbcled to form the shoulder (5, against which the ends oi" the lateral flanges of the angle bar abut. Those wall brackets are bolted or otherwise secured to the top of the wall oi the granary, as shown in Fig. *l.

It the object to eliminate all fastening bolts or rivets. us l ar as may be possible, and I have devised a. special l'orni of commotion :lor the inner ends of the angle bars which entirely dispenses with bolts or lnstemings to secure the inner ends of the angle bars in place.

The central casting comprises two parts. One part is formed with the collar 7 and the frusto-couical skirt 8, the angle of which corresponds to the desired pitch of the root. The other part of the centrlil casting is fitted over this and comprises the collar 9 sleeved on the collar 7. (last with the collar 9 is the skirt 10 which is shaped to form it series of radial sockets ll. It will be noted that the skirtb forms the bottom of these partsu "he skirt 8 is preferably formed with a series of radial slots 12, to receive the lower flanges ol the angle bars, as shown particularly in Fig. l. ll T-bars were employed these slots might be omitted.

(J11 each side of each slot I may form lugs 13 to press the lower flanges of the angle bars and to provide means for bolting the angle bars to the skirt 8, it for any purpose it become necessary to do so. In it granary rool however these lugs may usually be dis pensed with.

It will be seen that when the anglebars are inserted in the sockets ll, and the wall brackets 5 secured to the upper edge of the granary wall. that the angle bars and central casting will be securely hold in. position, the

only bolts required to be placed by the builder bring those securing the outer ends oil the angle lllllS to the granary wall.

The roof is iliorined oi a series of sectorshaped plates 14, each having its edges turned up to lorin lhe l'lung'cs 15. ,The end of each plate is preferably formed with a depending flange ll), which serves to prevent rain or snow being blown into the granary beneath the outer edges of the plates andL the edge of the wall of the granary.

lhe rool' means of the cap bars 17, which on reference to Fig. 7, it will be seen, embrace the flanges 15 and the plates of the sections and the upwardly extending. flanges ot' the angle 105 sections i l are held in place by hers. Tlhe edges 18 of the cap bars are preferahly turneddovvn, as shown, to engage, the root sections.- into the sockets 11 as shown particularly in Figs. 3 and Clhe'lovver end of each cap bar has an end casting 19 secured thereto.

When the cap bar is in place these end castings are'secured to the 'vvall brackets 5 by means of the bolts 20. "W hen these cap bars are in place the roof sections are securely" roof sections and caps are all readily pushed up into place between the shirts while the gradual narrowing of the sockets causes all the parts to be pressed tightly together as the caps are pushed into place. The shoulders 21. on the skirt 10 engage the cap bars. to press their edges tightly against the roof sections. The joints are thus made as secure against rain and line drifting snow as if soldered. The central opening in the con tral casting is covered by the ventilator S21 ofany desired type.

From the above description it will be seen that l have devised a roof construction which will satisfactorily accomplish the objects of my invention as set out in the pre amhle to this specification.

/Vhat I claim as my invention is 1. in a sheet metal roof the combination of radial angle bars each having two lateral. and one upwardly extending flanges; an apex casting having a tapered socket formed therein to receive the ends of the angle bars to support and he smaported' thereby; root sections having their sides supported on the lateral flanges of said angle hers and provided with side flanges adapted to lie against the upwardly extend- These cap ha'rs lit 1, messa- 52. in a sheet metal roof the combination of radial anglebars each havin two lateral and one upwardly extendlng anges; Wall brackets secured to the outer ends of the angle bars; an apex casting having tapered socket-s formed therein to receive the inner ends of the angle bars to support and he supported thereby; roof sections having their sides supported on the lateral flanges of said angle bars and provided with side flanges adapted to lie against the upwardly extending flanges of the ailgle bars; cap hars'iitting over said flanges. and having their innerends received in the sockets of the apex casting; and cap ends secured to the ends of the cap bars and bolted to the Wall brackets.
